一：准备软件包，存放/home/xiutuo/software/目录下。
主要软件包，
1. httpd-2.2.6.tar.gz
2. mysql-5.0.45-linux-i686-glibc23.tar.gz (这个版本是已编译好的压缩包，解压后稍做配置即可使用)
3. php-5.2.5.tar.gz
安装php所需的软件包（其中libxml2是安装php5必须的.）
1. libxml2-(version).tar.gz ---> http://ftp./pub/GNOME/sources/libxm2
2. libxslt-(version).tar.gz ---> http://ftp./pub/GNOME/sources/libxslt
3. curl-(version).tar.gz ---> http://curl./download
GD库所需要软件包（有人说PHP源码包里自带了GD2.0.28和zlib，只要安装GD的三个支持包：jpg,png和freetype，但是我们还是下载）
1. gd-(version).tar.gz ---> http://www./Main_Page or http://www./releases/
2. freetype-(version).tar.gz ---> http:///projects/freetype
3. jpegsrc.v6b.tar.gz ---> http:///files/jpegsrc.v6b.tar.gz
4. libpng-(version).tar.gz ---> http://www./pub/png/libpng.html
5. zlib-1.2.3.tar.gz ---> http://www.
把以上所有软件包下载到：/root/Software/目录下.
二：安装mysql
# tar -zvxf mysql-5.0.45-linux-i686-glibc23.tar.gz
# mkdir -p /usr/local/mysql
# cp -r mysql-5.0.45 /usr/local/mysql
# cp /usr/local/mysql/support-files/mysql.server /etc/rc.d/init.d/mysql //开机启动mysql
# cp /usr/local/mysql/support-files/my-medium.cnf /etc/my.cnf
添加mysql用户及用户组
# groupadd mysql
# useradd -g mysql mysql
修改mysql目录权限
# chown -R root /usr/local/mysql
# chgrp -R mysql /usr/local/mysql
# chown -R mysql /usr/local/mysql/data
生成mysql系统数据库
# /usr/local/mysql/scripts/mysql_install_db --user=mysql& //启动mysql服务
# /usr/local/mysql/bin/mysqld_safe --user=mysql&
如出现 Starting mysqld daemon with databases from /usr/local/mysql/data 代表正常启动mysql服务了.
按Ctrl + C 跳出修改 mysql 的 root 密码
# /usr/local/mysql/bin/mysqladmin -u root -p password "123456"
三：安装GD库(让PHP支持GIF,PNG,JPEG)
a.安装 jpeg6 建立目录：
如果选择默认安装,可能很顺利,指定路径后,请先创建以下文件夹，如果不创建文件夹，会报错
错误提示:...... /usr/bin/install -c -m 644 jconfig.h /usr/local/jpeg6/include/jconfig.h /usr/bin/install: 无法创建一般文件‘/usr/local/jpeg6/include/jconfig.h’: 没有那个文件或目录
接着，开始编译 jpeg-6b./configure --enable-shared --enable-static make可能出错 ./libtool --mode=compile gcc -O2 -I. -c ./jcapimin.cmake: ./libtool：命令未找到 make: *** [jcapimin.lo] 错误 127 首先看有没有安装libtool 及 libtool-ltdl-devel rpm -qa | grep libtool 然后进入jpeg-6b的源码目录，然后执行以下步骤，切记！ cp /usr/share/libtool/config.sub . cp /usr/share/libtool/config.guess . 也就是把 libtool里面的两个配置文件拿来覆盖掉jpeg-6b目录下的对应文件make clean 再重新configure没有权限的时候先建立对应的文件夹，再次make install就行了 安装如下：
# mkdir -p /usr/local/jpeg6
# mkdir -p /usr/local/jpeg6/bin
# mkdir -p /usr/local/jpeg6/lib
# mkdir -p /usr/local/jpeg6/include
# mkdir -p /usr/local/jpeg6/man
# mkdir -p /usr/local/jpeg6/man1
# mkdir -p /usr/local/jpeg6/man/man1
# cd /root/Software/
# tar -zvxf jpegsrc.v6b.tar.gz
# cd jpeg6
# ./configure --prefix=/usr/local/jpeg6/ --enable-shared --enable-static
# make
# make install
b.libpng包(支持PNG)
# cd /root/Software/
# tar -zvxf libpng-(version).tar.gz
# cd libpng-(version)
# ./configure --prefix=/usr/local/libpng
# make
#> make install
c.安装 freetype
# cd /root/Software/
# tar -zvxf freetype-(version).tar.gz
# cd freetype-(version)
# mkdir -p /usr/local/freetype
# ./configure --prefix=/usr/local/freetype
# make
# make install
d.安装zlib
# cd /root/Software/
# tar -zxvf zlib-1.2.3.tar.gz
# cd zlib.1.2.3
# mkdir /usr/local/zlib
# ./configure --prefix=/usr/local/zlib
# make
# make install
e.安装GD库
# cd /root/Software/
# tar -zvxf gd-(version).tar.gz
# mkdir -p /usr/local/gd2
# cd gd-(version)
# ./configure --prefix=/usr/local/gd2 --with-jpeg=/usr/local/jpeg6 --with-zlib-dir=/usr/local/zlib --with-png=/usr/local/libpng --with-freetype=/usr/local/freetype
# make
# make install
e.安装Curl库
# cd /root/Software/
# tar -zxf curl-(version).tar.gz
# mkdir -p /usr/local/curl
# ./configure --prefix=/usr/local/curl
# make
# make install
四：安装apache2
# cd /roo/Software/
# tar -zvxf httpd-2.2.6.tar.gz
# cd httpd-2.2.6
# mkdir -p /usr/local/apache2
# ./configure --prefix=/usr/local/apache --enable-modules=so --enable-rewrite
# make
# make install
# /usr/local/apache2/bin/apachectl -k start //启动apahce
用浏览器查看http://localhost,得到it works，说明apache已经配置成功了.
# /usr/local/apache2/bin/apachectl -k stop //停止apache
五：安装php5，php5必须有libxml2支持!
a. 安装libxml2
# cd /root/Software/
# tar -zvxf libxml2-(version).tar.gz
# cd libxml2-(version)
# mkdir -p /usr/local/libxml2
# ./configure --prefix=/usr/local/libxml2
# make
# make install
b.安装 libxslt (可选安装，你可以不安装)
# cd /root/Software/
# tar -zvxf libxslt-(version).tar.gz
# mkdir -p /usr/local/libxslt
# cd libxslt-(version)
# ./configure --prefix=/usr/local/libxslt --with-libxml-prefix=/usr/local/libxml2
# make
# make install
c.安装php5
# cd /root/Software/
# tar -zvxf php-(version).tar.gz
# mkdir -p /usr/local/php5
# cd php-(version)
# ./configure --prefix=/usr/local/php5 --with-apxs2=/usr/local/apache2/bin/apxs \
>--with-gd=/usr/local/gd2 --with-jpeg-dir=/usr/local/jpeg6 \
>--with-zlib-dir=/usr/local/zlib \
>--with-png-dir=/usr/local/libpng \
>--with-freetype-dir=/usr/local/freetype -\
>--enable-trace-vars --with-mysql=/usr/local/mysql \
>--enable-mbstring=all --with-curl=/usr/local/curl --enable-mbregex \
>--with-config-file-path=/usr/local/php5 --enable-ftp \
>--enable-soap --with-xsl=/usr/local/libxslt
# make
# make install
# cp php.ini-dist /usr/local/php5/php.ini （别忘记了呵呵）
六：重新配置apache2让他支持php
# cd /usr/local/apache2/conf
# vim httpd.conf
在LoadModule php5_module modules/libphp5.so
添加AddType application/x-httpd-php .php
OK,基本的安装已经完成.
重新起动APACHE:
# /usr/local/apache2/bin/apachectl start
如果重新起动APACHE出现:
Syntax error on line 232 of /usr/local/apache2/conf/httpd.conf: Cannot load /usr/local/apache2/modules/libphp5.so into server:
/usr/local/apache2/modules/libphp4.so: cannot restore segment prot after reloc: Permission denied
那就要按照下面的方法解决:
1.chcon -t texrel_shlib_t /usr/local/apache2/modules/*.so
2.编辑/etc/selinux/config，找到这段：
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - SELinux is fully disabled.
SELINUX=enforcing
把 SELINUX=enforcing 注释掉：#SELINUX=enforcing ，然后新加一行为：
SELINUX=disabled
保存，关闭。
编辑/etc/sysconfig/selinux，找到:
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - SELinux is fully disabled.
SELINUX=enforcing
如果SELINUX已经是 SELINUX=disabled，那么就不用改了，否则就把SELINUX=enforcing 注释掉，新加一行：
SELINUX=disabled
保存，退出。
ok，web环境apache2+mysql5+php5就介绍到这里。更详细的apache2的配置和mysql配置和php.ini的配置参考相应文档
